第- 4 - 页
EFI（with battery above 45A.h）-30～40°C。
Apply to sea level elevation，engine with carburetor in 4000m；engine with EFI in 5000m。
Engine must be installed and fixed on vehicle or testing-bed, assembled all
accessories and filled in enough correct lubricating oil and coolant.
1.5Effecttoenvironmentandenergy
Polluted air like COx、CxHy、NOx will be emitted when engine works and consumes
fuel.
1.6Safety
The temperature of working engine is high, people are not allowed to touch engine
to avoid scald.
Engine output shaft is a high speed spinning part, please install protecting plate
or cover to avoid hurt.
